Cosmic SL 65 23i Carbon Wheel

The Mavic Cosmic SL 65 Disc answers the question of whether 65mm is too much wheel for everyday riding. Adaptive Layup construction is a variable fiber placement that concentrates carbon where the rim takes stress and pulls it back where it doesn't, recovering weight from the depth without compromising the rim's ability to hold speed under load. The 23mm internal width and UST Tubeless Ready setup handle the surface variation that a race-depth wheel would otherwise struggle with on training roads.

What Our Gearhead® Experts Are Saying:

"Adaptive Layup is what makes 65mm a training wheel rather than a race-day-only decision. The weight savings at the rim change how the wheel accelerates out of corners and responds to surges, which is where depth wheels usually feel sluggish compared to a shallower profile."
